Type of dietary carbohydrate affects thyroid hormone deiodination in iron-deficient rats

Article Abstract:

Studies were made on the effects of various carbohydrate diets on the growth and thyroid hormone metabolism of rats, which were fed iron-deficient diets with varying carbohydrate contents. Finding shows that iron-deficient rats suffer impaired food efficiency and hepatic thyroxine monodeiodinase activity regardless of carbohydrate diet. The stimulation caused by a sucrose diet on onmonodeiodinase activity seems to be offset by iron deficiency. A diet of 70% cornstarch restores normal thyroid hormone metabolism better than a sucrose diet, which tends to lower food intake.

Soybean protein isolate and soybean lectin inhibit iron absorpiton in rats

Article Abstract:

Studies were made on the effects of soybean protein isolate (SPI) on iron absorption in rats, which were fed either SPI-based or casein-based diets. The SPI diets lowered intestinal iron absorption more than the casein-based diets. SPI diets with 8% D-galactose stimulated iron-to-liver ferretin incorporation without increasing absorption. Heat-treated SPI allowed slightly better absorption. Lectin with N-acetyl-D-galactosamine, such as Concanavalin A, greatly lowered intestinal absorption of ferrous iron but had no effect on ferric iron absorption.

Potential of diet therapy on murine AIDS

Article Abstract:

The effect of nutrition on murine acquired immunodeficiency syndrome was assessed by comparing disease progression in mice restricted to 60% of normal diets and those without food restrictions. A portion of the diets was replaced with lipids. Results showed that moderate energy intake restriction and fish oil supplements can delay the progression of the infection. This is attributed to the changes on the lipid composition of immunocompetent cell membrane which alter immune responses.
